Some people say that the higher your deck and more centered you are (Decks 6, 7, or 8 midship), the less movement you feel. Some people swear by the lower decks. I think generally speaking midship is a good bet. We've been only Deck 7 midship and forward. We personally prefer forward because (being kid-less), we are closer to the forward stairs which in turn is closer to the things we love the most: The Spa, Quiet Cove Pool (and bar), and the Nightlife district (Beat Street/Route 66). Next cruise, we are still forward but Deck 6.
